My Lagan Love
(lyrics by Joseph Campbell, aka Seosamh MacCathmhaoil)

Where Lagan stream sings lullaby
There blows a lily fair
The twilight gleam is in her eye
The night is on her hair
And like a love-sick lennan-shee
She has my heart in thrall
Nor life I owe nor liberty
For love is lord of all.

And often when the beetle's horn
Hath lulled the eve to sleep
I steal unto her shieling lorn
And thru the dooring peep.
There on the cricket's singing stone,
She stares the bogwood fire,
And hums in sad sweet undertone
The songs of heart's desire
